Frequently Asked Questions
Q: What are the benefits of the 6G glass structure compared to plastic options?
A: The 6G glass structure provides higher light transmission and scratch resistance. More importantly, glass does not deform under heat, completely avoiding the annoying focus drift issues common with plastic lenses in outdoor setups.
Q: How does the vertical and horizontal F.O.V. dynamic work on different sensor dimensions?
A: At a 5.7mm sensor width, it yields a full 185° Horizontal F.O.V., while a 3.6mm sensor height outputs a 148° Vertical F.O.V. If your sensor size changes, the output field of view will scale accordingly.
Q: Does this 3MP M12 wide angle lens include an integrated IR cut filter?
A: The standard model comes with a day/night coating. Depending on your system design, we can supply it with custom 650nm / 850nm IR filters or clear glass according to your production requirements.
Q: Can this lens handle close-range sorting operations in a warehouse?
A: Yes. With its 0.1m Minimum Object Distance (M.O.D.), it focuses incredibly close to moving parts, making it an excellent match for robotic assembly lines and sorting trays.
Q: What kind of distortion correction does this lens require?
A: Because it features a -94% fisheye distortion, it generates a classic ultra-wide barrel image. It requires a de-warping software algorithm to linearize the horizon if your project demands a flat rectangular video feed.
